Operation of this LSI
Transfers received data to on-
chip RAM
Calculates sum total of
received sum value and 1 byte
units of programming control
program transferred to on-chip
RAM
If sum is 0, transmits H'AA to
host
If sum is not 0, transmits H'FF
to host halts operation
Starts total erase of flash
memory
Transmits H'11 to host if total
erase processing is being
executed when total erase
status command is received
Transmits H'06 to host if total
erase of all blocks has been
completed when total erase
status command is received
If erase cannot be performed
when total erase status
command is received,
transmits H'EE to host and
halts operation
Branches to programming
control program transferred to
on-chip RAM and starts
execution.
